  • 8. Tractatus and science Verifiability as: - Demarcation criterion - Meaning criterion Metaphysics becomes nonsense Science proceeds by induction
  • 9. The problem of (with) induction The supposition that the future resembles the past, is not founded on arguments of any kind, but is derived entirely from habit. (David Hume, 1737)
  • 10. How does Popper avoid induction? • Theories are never verified: they remain conjectures • They have the form of universal statements: “wherever A, then B” given right initial conditions • No number of A & B can prove; one A & not-B can falsify: an asymmetry
